Specification of Letters Patent.

`vl atented Ang. 10, 1909.

Application filed August 8, 1908. Serial No` 447,578..

To all whcmr'it may concern:

. Be itknown that I, WALTR P. l'vlUnPI-IY, a citizen of the UnitedStates, and a resident of the eityof St. Louis and State of Missouri,have invented a new and useful Improvement in Carslioofs, of which thefollowing is a specication.

This invention relates 'to car lroofs and more particularly to thecarlines for support ing,r the same,

It has foritsprincipal objects to take up looseness dueto the. shrinkageof the wooden side plates o1" longitudinal timl ers to which the ends ofthe carlines are secured, and to overcome certain disadvantages of theusual supporting saddlesor attaching devices of metal carlines. p

In metal carline constructions, it is customary in some cases, to shapethe end portions of the carlines to fit over the side plates orlongitudinal timbers, and in other cases, the end portions of thecar-lines are secured to separate castings or saddle meml ers which areadapted to be fitted over said side plates. In practice, it has beenfound that such connecting devices become loosened from the wooden sideplates or timbers, due

-to the shrinkage thereof.

My invention, therefore, consists in a co1npensating member or Wedgewhich takes up such looseness, and it further consists in theconstructions, combinations and arrangev ments of parts .hereinafterdescribed and claimed.

In the accompanying drawings which form part of this specification, andwherein like symbols refer to like parts Wherever they occur, Figure 1is an elevation partly in section, showing a portion of a carlineembodying my invention; Fig. 2 is a top plan view thereof;. Fig. 3 is alongitudinal section through the end portion of the carline, connectingmember and side plate; and Fig. 4 is a detail view of a preferred formof co1npeneating member or wedge.

In the drawings, the carlinecomprises a metal angle member 1 havingsecured thereon a Wooden filler or` beam 2 to which the roofsuperstructure is fastened. l Obviously, l however, the carline may beof any other de cars 6 for the reception of scouring),A `bolts 7,whereby, said portion 5 may le secured flat- Wise against the inner faceof the side plate 3.v Gn the racket portion 5 is -an inwardlyprojecting' portion 8 of angular section corresponding to the section ofthe angle mein ler 1 to which it is rigidly rivetedor secured. Thewooden filler member 2 is also secured to the memrer 8 by va lfolt 9extending through the vertical' flange thereof as well as theintervening' vertical flange of thc ang-lo, meinler l. The endconnecting member 4 is also provided with a saddle portion 10 having adownturned outer end portion 11 so as to straddle the side plate 3.

Preferably, the portion 5 of the connecting member 4 is liollowed outand provided with an inclined inner face. 12 so as to acconnnog date aninsertible take-up member or wedge 13. Preferably, this wedge is madewith a ila't face adapted to lie llatwise against the inner face of thesideplate 3, and an inclined face, or ribs 14, corresponding' to theinclination of the inner face 12 of the portion 5 ofthe end connectingmember 4.

In. practice, the wedge 13 is made to fit freely within the pocketprovided therefor in the bracket portion 5 of the end connecting member4, and the angle of the opposinfr in-` clined faces of the Wedge andYocliet wall being slight, the Wedge will droplliy gravity and themotion of the car, thereby, constantly taking u all looseness due to theshrinka e extending portions 5 and 11 of the end connecting member 4. yThus, the rigidity of the roof structure' is maintained and many disareovercome.

Obviously, supplemental wedges or other devices may be made to coperatewith the single wedge shown, and the device may be otherwise .modifiedwithout departing from the invention. Therefore, I do not wish to belimited to the exact construction and arrangement shown.

What I claim is:

1. -A carline or the like comprising a saddle portion arranged tostraddle the side platev of a car, and means tending continuously andautomatically to take -up looseness between said side plate and saidsaddle portion.

2. A carline or the.A like comprisingcg` a saddle portion arranged tostraddle the side plate of a car, and a compensatinpr clement tendinglof the side plate between. the downward y` advantages due to loosenessof connectionsl continuously and automatically to take up loosenessbetween said side plate and said saddle portion.

3. A carline or the lilieco'mprising a saddle portion having downturnedmembers adapted to sti'addle the side plate of a car, one of saiddowntui'ned members having an incline opposite the face of said sidelate, and a v counterpart compensating mem er between said incline andthe opposing face of said side plate, said compensating member tendingcontinuouslyto take up the space between said incline and said sideplate.

4. A carline oi' thc like comprising a saddle portion having downturnedmembers adaptcd to sti'addle the side plate, of a cai', one of saiddownturned members havinv an incline opposite the face of said sideplate, and a movably mounted wedge element one face ol which bearsliatwise against said face of the side plate and whose other face bearsagainst said incline, said Wedge element tending' continuously andautomatically to take up an)v looscness that may occur between saidside. plate and said incline.

5. A cai'line or the like comprising means l'oiconnecting the same tothe side plate of a cai, said means comprising a gravitatmg deviceadapted to constantly take up looseesfeve Ainserted between said inclineand t e opposing face of said side plate.

8. A carline or the like comprisin an end connecting member. adapted toe vconnected to the side plate of a car, and a gravitating Wedge to beinserted between said side plate and said end connecting member.

In 'testimony whereof I have hereunto signed my naine in the presence oft'w subscribing witnesses on the 1st day of .August WALTER 1 MURPHY.
